jcarter -> 03 Silverado Radiator Flush (9/24/2007 12:25:45 PM)
|
Can anyone offer some advise on flushing the radiator on a 2003 Silverado with a 5.3 V8, 4WD? I can not find a radiator cap on the radiator, so I assume the only cap to worry about is the one on the overflow resivor. I have drained the radiator, but it doesn't seem like enough fliud has came out of the radiator. I also refilled (through the resivor) the radiator with a Prestone Flush and water. It did not seem that the system took as much fliud as what came out. Is there a way to bleed out any air in the system, or does it bleed out on its own? I have driven the truck for roughly 1 hour and it is not overheating and the fliud level in the resivor is normal. I am going to refill the system with Dexcool and I want to make sure that I am following the correct procedure.
Thanks for any help.
